Initiating nasal continuous positive airway pressure in preterm neonates at 5 cm as against 7 cm did not decrease the need for mechanical ventilation.

AIM: The optimum starting nasal continuous positive airway pressure (nCPAP) for infants on bubble nCPAP is unknown. We compared whether an initial bubble nCPAP of 7 cm rather than 5 cm of water prevented the need for mechanical ventilation among preterm neonates with respiratory distress.
METHODS: Preterm neonates born at 27-34 weeks with the onset of respiratory distress within 24 hours of birth were randomised to receive high or standard nCPAP at either 7 cm or 5 cm of water, respectively. The primary outcome was the need for mechanical ventilation in the first week of life.
RESULTS: The baseline characteristics were comparable between the two groups. The proportion of infants who required mechanical ventilation during the first week of life was similar between the two groups (standard 29/133, 21.8% versus high 30/138, 21.7%), with a relative risk of 0.99 and range of 0.56-1.77. The secondary outcomes were similar between the two groups, including mortality before discharge, pulmonary air leaks, need of surfactant therapy, bronchopulmonary dysplasia and duration of nCPAP.
CONCLUSION: Initiating nCPAP at a higher pressure of 7 cm in preterm neonates with respiratory distress, rather than the standard 5 cm, did not decrease the need for mechanical ventilation during the first week of life. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.
